自制口鼻双通道面罩在无痛胃镜中的应用*

目的探讨该科自行研制的口鼻双通道面罩在无痛胃镜术中的安全性和可行性。方法 400例患者接受丙泊酚与小剂量芬太尼复合静脉麻醉行无痛胃镜检查,患者随机分为两组,每组200例。对照组采用普通鼻导管4.0~5.0 L/min给氧;实验组采用口鼻双通道面罩4.0~5.0 L/min给氧。记录患者麻醉前和麻醉后呼吸次数(RR)、血氧饱和度(Sp O2)、麻醉药用量及检查时间,两组进行比较。结果对照组麻醉中Sp O2明显降低,检查时间延长,与实验组相比差异有统计学意义(P0.05),两组RR和麻醉药用量差异无统计学意义。结论在无痛胃镜检查中口鼻双通道面罩给氧优于鼻导管给氧,可安全应用及推广。

Application of a self designed oral-nasal double channel mask in painless gastroscopy*

Abstract: Objective To evaluate the feasibility and safety of self designed oral-nasal double channel mask in painless gastroscopy. Methods 400 patients who were given intravenous injection Sublimaze followed by Propofol were divided equally at random into two groups. The patients in control group (n = 200) were inhaled oxygen with snuffle tube (4.0 ~ 5.0 L/min) and the patients in experimental group (n = 200) were inhaled oxygen with a self designed oral-nasal double channel mask. Respiration rate, SpO2, duration of operation and dosage of anaesthetic were recorded before and during operation. Result The SpO2 decreased markedly and duration of operation obviously prolonged in group i during operation (P < 0.05), there was no statistical difference between the two groups of the respiration rate and dosage of anaesthetic. Conclusion The application of oxygen inhalation with the self designed oral-nasal double channel mask in painless gastroscopy appeared safer than that of oxygen inhalation via snuffle tube. It can be safely used in painless gastroscopy.
